A shared hosting account have some restrictions :

  • Daemon mode is forbidden, or cannot be activated. So you must use CGI mode.
  • You must fit in the server environment : OS version, libraries, installed packages.
  • The OS version is generally a stable version, but not the latest version.

Download a GeneWeb package

Directories and files

The following applies to 1&1 hosting, and may differ on other hostings: Under the root directory where CGI scripts may run, we have : !File:captur477.jpg

The directories :

? Beside the CGI-root directory
mybases The bases directory
? In the CGI-root directory
basesxg An alternative bases directory
css A copy of the gw/css directory. This directory is used by the Apache server.
gw The gw directory of the Geneweb distribution

No change, except give the "exec" permission on the files gw/gwd, gw/gwsetup, and files used by gwsetup (gw/gwc*, gw/gwu,gw/consang, gw/update_nldb) The gwd.arg file is *empty*.

gwenv The gw directory of the Geneweb-5 distribution

On this web site, we can easily switch between the 2 last versions of GeneWeb.

igw The images directory for Geneweb-5
images A directory where copies of gw/images/gwback.jpg, gw/images/gwlogo_bas.png
pub A directory where are readable copies of the CGI scripts (this website is a demo site) :

launch Geneweb-5 launch Geneweb-6 check if Geneweb-6 can be launched

And the files :

issue6.cgi A test script which

- displays information about the environment in the server - checks the gwd binary file : size and md5sum

issue5.cgi The same script, but for the GeneWeb-5 version
gw6.cgi The CGI script which launches GenWeb-6
gw5.cgi The CGI script which launches GenWeb-5

Parameters of the CGI script

<code class="PHP">

Main settings :

  • 1 get the CGI working directory
  • 2-7 set the main parameters
  • 5 $GENEWEBDB does not need to be accessed by the HTTP server.

It must be protected either by a .htaccess file, either by a location out of the HTTP server scope.

  • 7 a log file is useful when there are problems, but do not forget to delete it after downloading.
OPTIONS="-blang -robot_xcl 40,70 -max_clients 15 -conn_tmout 120 -min_disp_req 30 -images_url http://myserver.net/gw/images"
# -allowed_tags $GENEWEBDB/tags.txt

Options and launching

-robot_xcl to protect your data from HTTrack or WebSite Extractor
-conn_tmout for statistics on the bottom line
-images_url icons and images are not sent by GeneWeb, but par your HTTP server (not CGI).
-allowed_tags another useful option, if you use HTML tags not in default_good_tag_list
  • 3 cd $GENEWEBSHARE. I am not sure it is really needed.
  • 4 launch GeneWeb
